Most Facebook users have yet to experience its new look - the switchover will take months to complete - but details of the changes are starting to sink in.

The move is perhaps less shocking than the introduction of Timeline or Graph Search because many of the website's headline changes are already familiar to its app users.

Even so, marketers have been puzzling over what having bigger pictures means for the effectiveness of adverts, while the public has expressed mixed feelings about the promotion of news feeds and other changes.

Many have also noted Facebook's home page now looks more similar to that of its rival Google+, although in fairness it was less than a year ago that critics were highlighting that Google had "borrowed" some of Facebook's features for its social network.

This is a selection of the material published online in the hours after the California press conference announcing the revamp:

History has already shown that Facebook users don't take kindly to having more than one feed to look at, even if that feed is technically making their lives easier and removing some of the less important updates from the main feed.

Ads weren't discussed at all [at the press conference] which is where most of the clutter is. It will be interesting to see how advertisements evolve with this new design, and if we'll see more of them.

More screen real estate and more dynamic ads could spell immediate benefits for advertisers... A developer of social games may now have the ability to just advertise on the Games feed as opposed to the general News Feed. And multiple news feeds means the potential to serve more ads.

The biggest change Facebook announced today, from the perspective of publishers and the people who want to read them on Facebook, is the "following" tab [which] will show "every single post" from the people and publishers you subscribe to. If true, that will go a long way toward building trust in Facebook as a home for breaking news.

Users can choose from a list of topic-specific updates in addition to the main News Feed

Third-party applications are going to get a crack at showing richer content. This opens the door for existing applications that were hampered by the News Feed to show off better content, as well as leaving the door open to newer applications to be built to take advantage of the new, more visual News Feed.
